the map is alive

---

You might wonder, why is bro devlogging so often? Wellll, i had this whole plan i wrote down a bit ago to commit when so that it’s not a 10000 line commit (shudders in that happening before) but I severely overestimated how long these things would take

Most of the time not logged was testing, sigh i wish i could devlog that lolll

hehe okay so the notes actually live on a map now. like they have positions, computed by the real layout engine, and you can drag the whole thing around and zoom. it’s a canvas!! a real one!!

what and how

so on boot (native), it spins up the LayoutEngine, drops every note in as a node, restores their saved positions if there are any, feeds in the links, and runs the layout to settle everything. then it builds two things for the UI: note cards (with x/y from the layout) and edges (lines between linked notes, computed from the endpoint positions). both get shoved into Slint models and the map renders them. add a new note and it gets added to the layout, re-stepped, and the cards + edges refresh. positions save back to storage when you close the app.

the map-canvas.

slint got the fun part: pan and zoom. a TouchArea catches pointer down/move to drag the camera around, scroll wheel zooms between 10% and 500%, and every card positions itself as (card.x - camera) * zoom. threw in viewport culling too so cards way off-screen just don’t render (visible: only if it’s within ~200px of the edges). and a little “N notes | zoom: X%” readout in the corner because I like knowing things. (it’s broken like most of this, we ignore that for now, polishing is later)

my foolishness

the whole thing is cfg-split for wasm because the GPU layout engine isn’t wired up on the browser side yet, so wasm gets a fallback that just lists the cards without real positions for now. desktop gets the full living map, browser gets the placeholder, both compile, nobody’s angry. (the wasm map is a TODO-shaped hole but it’s an silly one.)

also had to expose universe.storage() so the UI can reach load_positions/save_positions, and added a small EdgeVM struct to carry line endpoints into Slint.
